Bernds Wunsch 2026-10-07: Die Nachrichtenliste reicht jetzt bis ganz unten; Tipp-Anzeige und Eingabefeld schweben darueber. Um das Feld herum ist die Flaeche klar (Chat sichtbar), aber beruehrungsdicht - dort reagiert nur die Eingabe. Hinter dem Feld selbst Milchglas (Unschaerfe + 78 % Flaeche), Rahmen und Fokus-Ring aussen. Die Liste bekommt unten genau die gemessene Hoehe der Leiste als Abstand (MeasureSize; waechst mit Antwort-Leiste/mehrzeiligem Text), damit die neueste Nachricht ganz ueber die Leiste scrollt; der Nach-unten-Knopf sitzt darueber.
